What is the specific function of a satellite in a chromosome ? How are sat-chromosomes different from others ? On molecular basis, what are the functional advantages of it ?
There are at least 2 SAT chromosomes in each diploid nucleus. They play a vital role in the formation of the nucleolus after cell division is completed.
In humans, chromosomes number 13, 14, 15, 21 and 22 are examples of SAT chromosomes.
